3d mouse does not work

 Heey,

I work with the bricscad v15 pro edition for my work. I have a 3dconeexion space mouse that works great with bricscad.
I use it with drawing 2d contstructions and i have nothing to complain only it stops working after some time.

The first few drawings give no problems but after i opened a few the movement with my 3d mouse stops.
The hotkeys are stil working but the movement not.
The drawings i opened before this happens still work like it should

please help me it is very annoying

Greetings

Jordy
